seldom

English

Old English seldan.

seldom (comparative more seldom, superlative most seldom)

infrequently, rarely.
They seldom come here now.
- 2013 April 9, Andrei Lankov, “Stay Cool. Call North Korea’s Bluff.”, New York Times:
  People who talk about an imminent possibility of war seldom pose this question: What would North Korea’s leadership get from unleashing a war that they are likely to lose in weeks, if not days?

It is grammatically a negative word. It therefore collocates with ever rather than never.

infrequently, rarely
